Answer:
Geometric Sequence
Step-by-step explanation:
In this case it is Geometric Sequence as it has a common ratio of 5
Formula for nth term: a(n) = ar∧n-1
so if we take the third term we will calculate as follows:
50 = 2(r)∧3-1
50÷2 = r∧2
√25= r
r=5
Answer:
3w+7
Step-by-step explanation:
Let's simplify step-by-step.
8v+w+7−8v+2w
=8v+w+7+−8v+2w
Combine Like Terms:
=8v+w+7+−8v+2w
=(8v+−8v)+(w+2w)+(7)
=3w+7
It would be 100. Hope it helps!
